But according to a new survey, nine out of 10 American young adults believe they follow a healthy lifestyle, but most eat too much fast food, drink too much alcohol and too many sugary beverages and have lifestyles that put them at higher risk of stroke, Medical News Today reports.

A true healthy lifestyle means eating a low-fat diet that is high in fruits and vegetables, keeping alcohol and sugar intake within moderate limits, getting regular exercise, not becoming overweight and not smoking.

"If we are not able to help young adults understand the relevance of their actions now and their risk of stroke tomorrow, then we could be looking at an increase in stroke diagnoses and deaths within the next 10 to 20 years," Dr. Ralph Sacco, neurologist and president of the American Heart Association/American Stroke Association, said in a statement.

Good news if you're 25-44: Eight out of 10 Americans in this group believe they have healthy lifestyles and are more likely to have healthy habits than those in the 18-24 age group.

But while most 18-24 year-olds said they wanted live to be about 98 (!) years old, one-third didn't believe that following an unhealthy lifestyle at their age would affect their risk of stroke later.

I think I have a pretty healthy lifestyle. I eat nutritious meals, drink plenty of water and juices and
I walk a lot and keep active. I fail to get enough sleep nowadays because I'm on SH way too many hours into the night and morning. That is my real downfall and I need to adjust the time I spend on my computer so I can get more rest.

I feel that back in High school i was more healthier. Now that I went to college I am eating more, and also more unhealthy things. I use to eat breakfast and now I can barely get up to eat lunch. Some docotor's say the worse time to eat is after nine and I find myself eating around 10 and 11 all the time. I try to eat less and I plan on trying to exercise more this summer and trying to loose some of the weight I put on this school year.

I've never really been into sugar, soda, junk food, ect. after a single incident: I was at a party, having fun and all, but then I ate too much and somehow managed to get food poisoning . . . barfing and being sick for so long was good enough to get me to stop eating so much junk food and sugar in general.
I weight lift 2-3 times a week, for 2 hours at a time, and run 3 times a week (2-3 miles), and make sure to spend lots of time off the computer. All this exercise was because I was overweight/obese for about 10 years of my life or so, and after getting into shape because of powerlifting, I'm really not willing to get out of shape again. As for alcohol, I'm not even old enough to drink it, nor would I want to. IT SMELLS SOOOOOOO NASTY! Smoking is pretty nasty IMO too, since I have a lot of relatives who smoke and the stuff makes me cough and gives me really bad headaches too.

If I use the definition of a healthy lifestyle found here then my lifestyle is very healthy. But, I'm not healthy. I'm disabled (arms, hands, neck) and have diabetes. Then again if it weren't for my healthy life style I might be a whole lot worse. As it is my heart's good, my cholesterol is perfect, my lungs are good and I can still dance from 10pm to 1pm. Not too bad for 53.

It's not unhealthy, but it's not the healthiest. I do Tae Kwon Do five days a week and most all of what I eat is healthy, but I do drink soda whenever I can and I probably eat too MUCH, even though it generally is healthy.

Go for it! Just don't' eat pizza more than once a week and never more than 2 pieces and you'll be fine. That was the down fall of my generation. Beer and pizza, 3 times a week before we were even 16. That made a lot of us very fat and gave us gallbladder stones. I escaped by limiting myself.
